Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (S)-2-methylbut-3-enoic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 100.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
(S)-2-methylbut-3-enoic acid (CAS 59014-11-8), molecular formula C5H8O2 and molecular weight 100.12 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
